In July 2009, British model Katie Green won a competition to represent Wonderbra and was referred to Premier Model Management. Green later said that a man connected with the Wonderbra public-relations operation told her she needed to lose weight and that being a UK size 8 was not acceptable for the work. According to Green, she initially tried to comply, but abandoned the agency after being told that further employment depended on reaching the demanded weight. Her account exposed the coercive economics behind the size-zero ideal: a model could be publicly celebrated by a major lingerie brand yet still be treated as commercially deficient because her body did not conform to an ever-narrowing sample size.
Green subsequently joined Liberal Democrat MP Lembit Öpik in launching the 'Say No to Size Zero' campaign. They sought 20,000 petition signatures for presentation to the British prime minister and Parliament and called for legislation requiring regular health examinations for models before assignments. The specific weight-pressure allegation remained Green's account rather than a judicial finding, but the campaign contributed to a broader British debate over agency power, medical screening, and whether fashion employers should be legally responsible for models' health.
